IMPROVEMENT IN FIRE-EXTINGUISHERSQ Specification forming part of LettersPatent No. 168,720, dated ctober 11, 18'75; application filed July 22,1875.

To all whom it may concern:

Be it known that I, BENJAMIN F. CLEMIN- SHAW, of Troy, in the county ofRensselaer and in the State of New York, have invented certain new anduseful Improvements in Fire- Extiuguishers; and dohereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accom- *panying drawings, and to the letters of referrhinging the acid-bottle thereto in such a manner that its mouth will heclosed by the gravity of the bottle when the extinguisher is not in use,and will automatically free itself from the valve and empty its contentswhen the ex tinguisher is reversed, all as more fully here inafter setforth.

The figure in the drawings represents a sectional view of the entireapparatus, showing the same when not in use.

A represents the usual soda chamber or cy]- inder, having the usual plugO, with stopcock a and exit-hose D. The top of this cyl inder has ascrew-opening, into which the cap or plug E is screwed Attached to theunder central part of this cap is an inclined plate, Gr, which isprovided with an under coverng of leather, rubber, or other suitablematerial, the two forming a valve to close the open end or mouth of theacid-bottle. Hinged to ears extendn g from the bottom of the plug, nearthe valve Gr, is a frame, H, into which the acidbottle K is placed. Whenthis bottle is filled the weight of the same will cause it to press themouth of the bottle close against the valve in the manner shown in thedrawings, making a perfectly air-tight joint. When the cylinder isreversed for us e the bottle will free itself from the valve and emptyits contents into the soda-chamber, and form the gas for extinguishingfires, in the usual manner.

By this construction the apparatus is easily, operated, and the partscan be quickly charged for use. The plug E, valve D, and frame E[, with'bottle K, are all connected, and, by simply unscrewing the plug, theyare all extracted together from the cylinder, so that the .filling canhe accomplished and the parts replaced at once.

I do not claim the stopper having a flaring rim attached thereto, assuch is not my invention.

What I claim is The nclined stationary valve Gr and the frame H, hingedto the cap E, and containing the acid-bottle K, in combination with thechamber A, all substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this5th day of July, 1875.
